A turbine with a power coefficient Cp = 0.28 is able to generate 2.1 MW of electrical power with blades of length R =75 m. What is the value of the wind speed? Calculate the value in meters/second and round off to two decimal places. Do not write the unit.

In a system where the Froude model will be used, the flow rate for the prototype is given as 3 m3 / s. In the model, the velocity at point A is 0.2 m / s and the force acting on point A is calculated as 1 N. Calculate the flow rate and velocity of the point corresponding to point A in the model and the magnitude of the force affecting the same point. Determine the pressure scale. The geometric scale will be taken as 1/100. Fluids used in the model and prototype are the same and are water

Water steam is running through the nozzle. Inlet pressure is P1=25 bars; T1=300C; V1=90m/s; A1=0.2m2. The exit parameters are: P2=11bars; T2=210C. The mass flow rate is m=2 kg/s. Determine: a.Exit velocity V2=?; b.Inlet and outlet diameters D1 and D2.

5.6 The x component of velocity for a flow field is given as u = Ax²y² where A = 0.3 m3 s and x and y are in meters. Determine the y component of velocity for a steady incompressible flow. Determine the equation of the streamline and plot the streamline that goes thrquek. the noint (x.y)=(1,4).
